' CONDENSER I FOR HECTOR-VEHICLE -RADIATGRS.

Applicati'on filed-August 27, 1923. Serial 310.6533610.

To all 10710122. iii-may concern:

Be it known that we, RANDALL D. GRIF- rum and CHARLES Soo'r'r IIUNTER,citizens of. the United States, and residents of Des Moines, in thecounty of Folk and State of Iowa, have invented acertain new and useful.Condenser for htiOtOT-VQhiCle vRadiators, of w ich the following is aspecification.

The object ot-our-invention is to provide a condenser for motor vehicleradiators.

Moreparticularly-it isour object .to pro vide a condenser adapted to bemounted on the radiator cap and comn'iunicating with the interior ofthe-radiator, which condenser is of simple, durable and inexpensive andI Jconstruction for causing the condensation particularly i' alcoholvapors, and causing the liquid of condensation to (low back into theradiator.

With these and other objects in View, our invention consists in theconstruction, arrangement and combination of the various parts of ourdevice, whereby the objects conten'iplatcd are attained, as hereinaftermore fully forth, pointed out in our claims, andillustrated in theaccompanying drawings, in which: 7

Figure 1 shows a front elevation of a radiator cap and condenserembodying our invention.

Figure 2 shows a side elevation of the same. i

Figure 3 shows a horizontal, detail, sectional view taken on the line 33of Figure 1. v

Figure 21; shows vertical, sectional view tel-zen on the line 1--4cofFigure 2; and

Figure 5 shows a vertical, sectional view taken onthe line 5 5 of Figure4.

It is well-known that in some types of automobiles, particularly theFord, the contents of the radiator become very hot and in winter whenalcohol is used with water as a non-freezing solution for the radiator,

the alcohol vaporizes rapidly and is lost in the form of vapor.

we have provided a condenser of novel structure for receiving the vaporfrom the radiator, condensing it and causing the liquid of condensationto flow back into the radiator.

Our improved condenser is used in combination with a radiator capindicated in the accompanying drawings by the reference character 10.

Our improved condenser comprisesahollow body or member 11 preferablycomposed A. B and C somewhat like starpoints.

The lower part of the body 11 is larger and all the parts are soarranged. as to drain toward a common point D.

A tube 13 is received in a suitable open' ing 1% in the upper part ofthe cap and has a nut 15 screwed on its lower end and an annularshoulder 16 above the cap.

The lower central portion ofthe body or member 11 is tapered from sideto side to the connecting edges except at the common point D, where themember 1]. is shaped to snugly receive the tube 13 to which the sides ofthe member 11 are thus fitted, so that the tube 13 serves to reinforceand strengthen the member 11.

The tube 13 is open at its upper end as at 17, which projectssubstantially upwardly into the hollow interior. of the member 11.

The tube 13 is provided with one or more openings 18 just above thecommon lower point D, so as to permit free drainage of the liquids ofcondensation from the member 11 into the lower part of the tube 13.

In the practical use of our improved condenser, the alcohol and steampasses upwardly from the radiator into the cap 10 and through the tube13.

The greater part of these vapors pass from the upperend 17 of the tubeinto the member 11 and diifuse through all .parts of the member 11including the projecting points A B and C. V

The meniber'll with its projecting hollow portions is subjected tocurrents of passing cool air, resulting inthe condensation of the vaporsin the condenser.

All the star points and the lower part of the member 11 are so arrangedas to drain toward the common point D, where the liquids pass throughthe openings 18 and downwardly through the tube 13 to the radiator.

The thin walls 01 the member 11 and the material and constructionthereof are such that it some slight pressure should exist in the member11, the Walls may spread somewhat toward and from each other at theircentral parts.

The condenser may be made in a variety of forms, either in combinationWith the cap or as a separate attachment, and it is not our intention tolimit ourselves to the particular form of condenser disclosed herein,and it is our purpose to cover by our claims any modified forms ofstructure or use of mechanical equivalents, which may be reasonablyincluded within the scope 0t our claims.

e claim as our invention:

1. In a condenser of the class described, a hollow member havingprojecting hollow portions, adapted to drain to a common point, a tubeentering said member at said point and projecting substantially intosaid member, open at its inner end and adjacent to said point andserving to reinforce the walls of said member.

2. In a condenser of theclass described, a hollow member havingprojecting hollow portions and comprising spaced resilient wallsconnected at their edges and capable of some movement toward and fromeach other except at said edges, adapted to drain to a common point, atube entering said member at said point and projecting suh stantiallyinto said member, open at its inner end and adjacent to said point andserving to reinforce the walls of said menr ber. v

3. In a condenser of the class described, a hollow member havingprojecting hollow portions adapted to drain to a common point, a tubeentering said member at said point and projecting substantially intosaid member, open at its inner end and adjacent to said point andserving to reinforce the walls of said member, and a radiator capmounted on said tube, having the tube projected through it.
